Vercel AI SDK

Vercel AI Gateway is a managed service from Vercel that routes application requests to language-model providers, centralizes API key management, and provides observability, caching, and rate-limiting for LLM usage. It is intended to simplify integration of multiple LLMs and enforce access controls for apps and autonomous agents.

Vertex AI is Google Cloud’s managed platform for developing and deploying machine-learning and generative-AI applications. It provides hosted models and APIs that applications, including agents, can call at runtime, along with tools for model training, evaluation, and serving.

Vercel is an application and agentic infrastructure platform for deploying and hosting web applications, marketing sites, platform products, and AI agents. Its infrastructure includes global delivery, deployment environments, serverless functions, fluid compute, a web application firewall, durable orchestration, sandboxed environments, and an AI model gateway. For hosted platforms, Vercel provides tenant isolation, domain management, custom SSL certificates, and preview URLs.

Vercel Connect is a Vercel service for connecting autonomous agents and applications on the Vercel platform to external systems, APIs and event sources while mediating and restricting data and event access. Developed by Vercel as part of its agentic infrastructure, it provides connectors and permission controls that determine what data and events an agent can read, transmit, or act on. The service is exposed via Vercel's agent framework and platform APIs and runs on Vercel's hosting infrastructure.

An Apache-2.0-licensed open-source Go SDK from Grafana for building AI-powered backends and agents. It provides GenerateText and StreamText APIs for calling language models, returning complete or streamed responses, executing Go functions as tools, generating schema-validated structured output, and running multi-step tool workflows, with approval for consequential tool actions. The SDK supports Anthropic, Amazon Bedrock, OpenAI, OpenAI-compatible APIs, and Grafana's hosted endpoint, along with retries, configurable timeouts, fallbacks, logging, Prometheus metrics, and Agent Observability. It follows the design of Vercel's AI SDK and is wire-compatible with its TypeScript React frontend hooks, including useChat, useCompletion, and useObject, allowing Go backends to stream Server-Sent Events directly to an existing React frontend without a protocol adapter.
